<p>PURPOSE:To not only project ultraviolet rays but also enable an erasing electrically on the erasing by combining a diode with a floating-gate. CONSTITUTION:A diode is combined with a floating-gate. Consequently, when a diode 7 for the floating-gate section is biassed in the opposite direction, only a memory element section is effective in the floating-gate 4, and charges can be stored temporarily as a floating-gate type nonvolatile memory element. When the floating-gate 4 section is biassed in the forward direction, on the contrary, charges stored in the memory element section can be discharged.</p> |
